IMPROVEMENT IN DOMINOES.

Specification forming part of Letters Patent No. 197,003, dated November13, 1877 application filed May 1, 1877.

To all whom it may concern:

Be it known that l, EDWARD ALDOM, of Brooklyn, E. D., county of Kings,and State of New York, have invented certain new and useful Improvementsin Dominoes, of which the following is afull, clear, and exactdescription, reference being had to the accompanying drawings, and tothe letters of reference marked thereon.

Figure l is a plan view of the domino blank or body, showing the same asit appears before the pip, cross-bar, and pivotal point are inserted;and Fig. 2, a similar view with these parts in place. Fig. 3 is an axialsection taken upon line a: of Fig. 1, and Fig. 4 a similar section uponline w m of Fig 2. Fig. 5 is an enlarged elevation of the pivotal pointas it appears when detached. Fig. 6 is an enlarged sectional elevationof one of the pips, showing its form before insertion in the dominoblank or body. Fig. 7 is an enlarged section of one of the pips and asmall portion of the domino, exhibiting its appearance when properlyseated. Fig. 8 is a perspective view of the completed domino.

Like letters in all the figures refer to corresponding parts.

The object of my invention is to simplify and improve the constructionof the domino, (well known as a 'card or piece used in the game calleddominoes,) and to diminish the cost of manufacture and increase thedurability thereof, to accomplish all of which it (the invention)consists in certain peculiarities of construction and combinations ofparts,as will be hereinafter fully described, and then pointed out inthe claims.

A is a rectangular block of wood,which I prefer to saw or otherwise cutinto proper shape and size. lt may be of any kind or quality suitablefor the purpose, and, after being cut, is stained black by anywell-known process. Either before or after staining, as may be foundmost desirable, the blank is perforated to receive the pips and pivotalpoint, and a slot cut in the top at right angles to the axis of theblock, to receive and hold the divisionstrip or cross -bar commonlyfound in or marked upon all dominoes.

In Figs. l and 3, a c, 8vo., indicate the perforations intended toreceive the pips 5 b, the slot for the cross-bar, and c the hole for thepivotal point. These additions or trimmings for the blank or body areall made of metal, and are held in place by simply forcing them into theproper receptacles provided for them. Being of metal, they are much moredurable than pearl or the like materia-l employed in the more expensivestyles of dominoes, and, being secured without the use of glue orcements, are not liable to become detached by accident or from theeffects of heat and dampness.

The pip d, (shown detached in Fig. 6,) being properly located over thehole a, is forced to its proper position by a suitable implement. Therim or edge of the indentation in the top of the pip, as is plainlyshown, projects a trie above the face of the blank, affording aprotection for the uppermost portion of the perforation a, wherebychipping and defacement of the card in that locality are obviated.

In order that the pivotal point e may be lo* cated in the center of thedomino, the crossbar f should be divided into two parts; but, for allessential purposes of the invention, the pivot may be placed at one sideof said bar, or the bar may be moved to one side a trie. The bar f beingforced into the slot provided for it, the pivotal point e is thensuitably A seated. The head of the latter will project over the formerand serve to sustain it in its proper place, although it (the bar) isintended to t its groove or slot quite tightly, so that it will be in nodanger of ever becoming displaced from ordinary accident.

As a matter of course, the pips are arranged in the customary order uponthe faces of the cards or domino-pieces. As thus constructed the dominois capable of being very cheaply made. It is obviously more durable thanthose wherein the pip is simply inlaid, or where the same is made bycoloring or painting, and the general appearance of the card or dominois much better than that of the latter class.

Having now fully described my invention, what l claim as new, and desireto secure by Letters Patent, is

1. The combination, with the Wooden body In testimony that I claim theforegoing I A, of the metallic pips a, held therein in the have hereuntoset my hand in the presence of manner and for the purposes set forth.two witnesses.

2. The herein-described domino, consisting of the perforated blank outfrom the natural Wood, and the metallic pips, cross-bar, and Witnesses:pivotal point, secured thereto in the manner HERMAN JOSEPH, shown anddescribed. CHARLES RAUBS.

EDWARD ALDOM.
